Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable where high voltage bulk capacitance is required.
• Snap‑in Radial Can Package — Snap‑in terminal mounting in a 22 mm × 30 mm can format for secure PCB installation in high‑current assemblies.
• Ripple Current Performance — Rated ripple handling of 740 mA at 120 Hz and 1.058 A at high frequency (50 kHz), enabling effective AC ripple absorption under DC bias conditions.
• Leakage Current — Specified leakage current of 770 µA, measured after rated voltage application, for predictable static performance.
• High‑Temperature Endurance — 2000 hours rated life at 105°C with defined endurance criteria for capacitance, tan δ, and leakage current.
• Operating Temperature Range — −25°C to +105°C suitable for elevated ambient environments encountered in industrial power electronics.
• Packaging & Production — Supplied in tray packing and available in mass production quantities for dependable supply chain integration.

Typical Applications

• High‑voltage power assemblies — Use where a 450 V rated capacitor and 150 µF bulk capacitance are needed for DC bus support and energy buffering.
• Ripple current management — Apply in circuits requiring controlled ripple absorption under DC bias, leveraging the 740 mA (120 Hz) and 1.058 A (50 kHz) ripple ratings.
• Elevated‑temperature environments — Suitable for power electronics modules operating up to 105°C where long life (2000 h at 105°C) is required.

Unique Advantages

• High voltage rating: 450 V capability enables fewer series components in high‑voltage designs and simplifies voltage margin planning.
• Strong ripple handling: Specified ripple currents at both low and high frequencies provide designers with quantifiable margins for AC stress management.
