Key Features

• Voltage & Capacitance — 400 V rated voltage with 120 µF nominal capacitance and ±20% tolerance (measured at 120 Hz, 20°C).
• High‑Temperature Long Life — Rated for operation up to 105°C and specified for 10,000 hours lifetime at 105°C under rated ripple conditions.
• Snap‑in Radial Can Package — Snap‑in mounting type in a radial, can-style package for secure board or chassis installation.
• Polarized Electrolytic — Polarized construction for applications requiring electrolytic capacitance at high voltage.
• Ripple Current Performance — Rated ripple current of 750 mA at 120 Hz and 1.073 A at 50 kHz; frequency coefficient data for rated ripple current is provided in the datasheet.
• Operating Range — Specified operating temperature range of −25°C to +105°C for the 400 V rating.
• RoHS Compliant — Manufactured in compliance with RoHS directives.
• Compact Dimensions — Physical size approximately L: 2.5 × D: 3.0 cm suitable for space-conscious assemblies.

Typical Applications

• General Purpose — Intended as a general-purpose high-voltage capacitor for designs that require 400 V rating and 120 µF capacitance with snap‑in mounting.
• High‑Temperature Environments — Suitable for installations where extended operation at or near 105°C is expected, supported by a 10,000‑hour endurance specification.
• Boards and Chassis with Snap‑in Mounting — Snap‑in radial can format for applications that favor mechanical stability and ease of board or chassis installation.

Unique Advantages
