Key Features

• Electrical — Capacitance & Voltage: 220 µF rated capacitance at 450 V provides energy storage for high‑voltage circuits.
• Tolerance & Polarization: Capacitance tolerance ±20% (at 120 Hz, 20°C); polarized construction for DC applications.
• High‑Temperature Endurance: Designed and specified for 5000 hours at 125°C to meet long‑life endurance requirements.
• Ripple Current Ratings: Rated ripple current of 1.12 A at 120 Hz (125°C); high‑frequency ripple value 1.602 A at 50 kHz, enabling defined performance across frequency ranges.
• Leakage & Loss Characteristics: Leakage current specified by I ≤ 3√CV (µA) following 5 minutes at rated voltage and 20°C; tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C.
• Temperature Stability: Category temperature range −40°C to +125°C with low‑temperature impedance stability defined (Z(−25°C)/Z(+20°C) ≤ 8 at 120 Hz).
• Mechanical — Snap‑In Radial Can: Snap‑in terminal, radial can package (size φD × L: 30 × 30 mm / L: 3 × D: 3 cm) for secure through‑hole mounting.
• Environmental Compliance: RoHS compliant per the directive noted in product documentation.

Typical Applications

• General‑Purpose Power Modules: For power assemblies that require a 450 V, 220 µF snap‑in electrolytic with long‑life, high‑temperature capability.
• Industrial Equipment: Suitable where sustained operation at elevated ambient temperatures and reliable DC energy storage are necessary.
• Power Conversion and Filtering: Fits designs needing defined ripple current handling and stable electrical characteristics over temperature.
• Control and Instrumentation Systems: Use in systems that benefit from RoHS compliance and long‑term endurance at up to 125°C.

Unique Advantages

• High‑temperature long life: Specified endurance of 5000 hours at 125°C supports longevity in heated environments and reduces maintenance frequency.
• High voltage capability: 450 V rating enables use in higher‑voltage DC circuits without stacking or additional derating.
• Clear ripple specifications: Provided ripple current ratings at both low and high frequencies allow predictable thermal and electrical design margins.
• Through‑hole snap‑in package: Radial, snap‑in can simplifies board retention and mechanical stability in power modules.
• Measured electrical limits: Leakage current defined by a standard formula and tan δ capped at 0.20, giving verifiable loss and leakage characteristics for design validation.
• RoHS compliance: Meets environmental directive requirements for assemblies needing restricted‑substance compliance.
