Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• High‑Temperature Long Life — Designed for operation from −40°C to +125°C with an endurance specification of 5000 hours at 125°C under D.C. bias plus rated ripple current.
• Snap‑in Radial Can Package — Snap‑in terminal type for secure mounting and robust mechanical retention in power assemblies; package dimensions approximately L: 5.5 × D: 3.0 cm.
• Ripple Current Capability — Rated ripple current of 1.84 A at 120 Hz (125°C) with frequency coefficients defined for higher frequencies; measured high‑frequency ripple performance listed at 2.631 A at 50 kHz.
• Leakage Current & Loss — Leakage current conforms to I ≤ 3√CV (μA) after 5 minutes at 20°C; tangent of loss angle (tan δ) is 0.20 max at 120 Hz, 20°C.
• Low‑Temperature Stability — Impedance stability characterized by Z(–25°C)/Z(+20°C) ≤ 8 at 120 Hz.
• Endurance & Shelf Life Criteria — After endurance testing (5000 h at 125°C with rated ripple and DC bias) and shelf life conditioning (1000 h at 125°C then voltage treatment), capacitance and leakage remain within defined limits specified in the datasheet.
• Polarized — Polarized electrolytic construction for DC smoothing and energy storage roles.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power equipment — Bulk smoothing and energy storage in high‑voltage power supplies and industrial power modules that require 450 V components with sustained high‑temperature operation.
• High‑temperature environments — Circuits that operate near or up to 125°C where long life and reliable ripple handling are needed.
• Ripple‑intensive circuits — Applications requiring capacitors with defined rated ripple current at 120 Hz and improved high‑frequency ripple performance for stable voltage filtering.

Unique Advantages

• 125°C long‑life assurance: Endurance rated 5000 hours at 125°C provides predictable performance in elevated temperature applications.
• High voltage capability: 450 V rating enables use in higher‑voltage DC link and power supply designs without series stacking.
• Robust ripple performance: Rated ripple current of 1.84 A at 120 Hz with frequency coefficients for higher frequencies supports heavy ripple environments.
• Measured electrical stability: Tight specified limits for tan δ, leakage, and low‑temperature impedance give clear performance expectations for design validation.
• Snap‑in mounting: Snap‑in terminals simplify secure PCB or chassis installation in power assemblies.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for deployed systems.
