Key Features

• Core Type Polar aluminum electrolytic capacitor in a radial, snap‑in can package suitable for board mounting.
• High Voltage Rating Rated for 450 V operation, enabling use in high‑voltage power circuits and bulk smoothing applications.
• Capacitance and Tolerance 120 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable bulk storage behavior.
• Extended High‑Temperature Life Endurance specified at 20,000 hours at 105°C under DC bias plus rated ripple current, supporting long service intervals and equipment longevity.
• Ripple Current Performance Rated ripple current 720 mA at 120 Hz (105°C) and 1.03 A at 50 kHz, with frequency coefficients defined for higher frequency operation.
• Operating Temperature Range Specified for −25°C to +105°C operating range to handle a broad set of industrial ambient conditions.
• Mechanical Dimensions & Mounting Snap‑in mount, radial can size φ35 × 25 mm (D × L), designed for secure PCB installation in power assemblies.
• Regulatory Compliant with the RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Smoothing — Bulk filtering and smoothing in high‑voltage power supplies where 450 V rating and 120 µF capacitance stabilize DC rails.
• Industrial Power Electronics — Energy buffering and ripple management in industrial converters and control equipment operating up to 105°C.
• Inverter and Motor Drive Support — DC link and smoothing duties in general‑purpose inverter assemblies requiring long‑life capacitors.

Unique Advantages

• Long Life Assurance: 20,000 hours at 105°C under rated conditions reduces maintenance frequency and extends system uptime.
• High Voltage Capability: 450 V rating enables use in higher‑voltage designs without series stacking, simplifying BOM and layout.
• Board‑Ready Snap‑In Package: Radial snap‑in can (φ35 × 25 mm) provides secure, robust PCB mounting for power modules and assemblies.
• Defined Ripple Performance: Rated ripple current figures (720 mA at 120 Hz; 1.03 A at 50 kHz) with frequency coefficients allow predictable thermal and lifetime planning.
• Wide Operating Temperature: −25°C to +105°C rating supports deployment across varied ambient conditions in general‑purpose equipment.
• RoHS Compliant: Meets current RoHS directive requirements for environmentally conscious designs.
