DL provides not only standard components but also custom engineering solutions. Our self-developed intelligent design platform speeds up product validation cycles from concepts to production.
Utilizing our AI-driven design environment, we simulation-test electrical behavior, thermal expansion, and mechanical stress models to adapt configurations to customer needs in record time.
From micro-pitch PCB connectors to high-voltage film capacitors, we cover UAV flight controllers, telecom power supplies, and critical life-support medical devices.
We focus on high-reliability technologies to overcome current bottlenecks in energy density, data attenuation, and environmental limitations.
We work to improve capacitor energy density with ultra-thin metallized film and advanced composite dielectrics, ensuring safe self-healing properties under high voltages.
We combine high-performance capacitors with high-density interconnects, optimizing transient response and power delivery in challenging environments.
Driving clinical reliability with material research, thin-film engineering, and advanced manufacturing processes.
Medical devices depend heavily on capacitor stability. For instance, external defibrillators require sudden energy discharge (up to 360 Joules) in milliseconds. Our research focuses on increasing the breakdown voltage and energy density ($J/cm^3$) of metallized polypropylene (PP) and polyester films.
By optimizing dielectric film thickness to less than 2.5 microns and utilizing advanced zinc-aluminum metallization profiles, we improve energy storage efficiency. This minimizes footprint while preserving the capacitor's self-healing properties under high-voltage stresses.
Our current roadmap focuses on high-k polymer nanocomposites that can operate at higher temperatures without thermal runaway, supporting smaller portable medical systems.
For diagnostic equipment like MRI and CT scanners, maintaining signal purity is essential. Dynalink designs ultra-low ESR and ESL Multi-layer Ceramic Capacitors (MLCCs) that utilize non-magnetic copper terminations to prevent artifacts during MRI imaging.
For implantable devices like pacemakers and implantable cardioverter-defibrillators (ICDs), our R&D team targets wet-tantalum design architectures. These offer high volumetric efficiency, low DC leakage current (DCL), and long operational lifespans under human physiological conditions.
Targeted capacitor and connector integration across diagnostic, therapeutic, and clinical applications.
High-voltage pulse discharge capacitors configured for biphasic waveforms. Capable of delivering 200J to 360J within 2 to 10 milliseconds, maintaining low dissipation factors under repeated discharge cycles.
Non-magnetic capacitors designed for gradient coil power amplifiers and RF transmit-receive channels. These minimize magnetic field distortions to support clean diagnostic imaging.
High pulse repetition rate capacitors designed for electrosurgical units (ESU) and laser scalpels. Engineered for low thermal drift and low ESR to prevent overheating during prolonged surgeries.

Compliance documentation and quality certifications required for global medical device approvals.
Medical electronics are subject to strict regulations. Components used in clinical environments must comply with international standards such as IEC 60601-1 (medical electrical equipment safety) and ISO 13485 (medical devices quality management systems).
Dynalink supports customers with localization efforts, offering cleanroom assembly options, comprehensive materials traceability, and test documentation to simplify FDA 510(k) and EU MDR filings. Our engineering documentation, material safety data sheets, and certification records support your regulatory path.
To meet Class II and Class III medical requirements, we offer:
Combining automation, real-time quality control, and robust sourcing to deliver consistent components.
Our smart manufacturing facility operates under an advanced Manufacturing Execution System (MES), linking material preparation, winding, metal spraying, curing, and final electrical characterization.
By producing critical sub-components in-house, Dynalink controls the manufacturing process and mitigates supply chain risks. We source specialized polymer films from vetted suppliers, keeping buffer stocks of strategic raw materials to isolate production from global logistics disruptions.
Every medical-grade capacitor lot undergoes standardized stress testing—including high-temperature burn-in, insulation resistance verification, and equivalent series resistance testing—ensuring reliability before delivery.
Technical criteria for supply chain managers and design engineers integrating ODM medical components.
Medical systems often have product lifespans exceeding 10 years. Dynalink offers End-of-Life (EOL) management, guaranteeing component availability or drop-in redesign options throughout your product's lifecycle.
When space is limited, custom terminals, mounting brackets, and specialized housing footprints are critical. We design custom mechanical layouts to integrate with existing chassis geometries.
Every shipment is backed by performance metrics, including capacitance distribution curves, leakage current readouts, and dissipation factor values, simplifying incoming quality control.
We maintain quality standards to meet global industrial, electronics, and safety requirements.
Answers to common design, engineering, and manufacturing questions for medical-grade capacitors.
Self-healing is a safety feature in metallized film capacitors. If a dielectric breakdown occurs from a voltage spike, the thin metal electrodes around the breakdown point evaporate due to the heat of the arc. This isolates the short-circuited area, restoring the capacitor's insulating properties within microseconds. This prevents catastrophic failures in life-support equipment like defibrillators, ensuring the system remains functional.
Standard electronic components often contain nickel or steel in their lead frames, terminal plating, or caps, which can cause image artifacts or dangerous mechanical attraction in strong magnetic fields. Dynalink's MRI-grade components use non-ferrous materials (like specialized copper-tin alloys or silver-palladium terminations), keeping relative magnetic permeability ($\mu_r$) close to 1.0. This prevents field distortion and protects imaging accuracy.
We trace components back to the raw film rolls and metallic spray batches. Each manufacturing step is recorded in our MES. In addition, medical-grade batches undergo specialized testing, including high-voltage burn-in at maximum rated operating temperatures, partial discharge testing, and seal integrity checks for hermetic housings. This helps prevent early component failures.
Yes. Our ODM capabilities include customizing capacitor shapes (such as flat-pack, cylindrical, or modular structures) to fit space-constrained medical designs. We can adjust the terminal configurations (threaded studs, PCB pins, flexible copper lugs) and case materials (polycarbonate, epoxy-filled cases, hermetically sealed aluminum cases) to match your application's requirements.
For metallized film medical capacitors stored under controlled conditions (temperature, humidity), the shelf life can exceed 10 years without significant degradation. Unlike liquid electrolytic designs, our dry film and oil-impregnated film structures resist drying out, providing long-term reliability for emergency equipment like Automated External Defibrillators (AEDs).
