Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 100 V for bulk energy storage and smoothing in high‑voltage DC circuits.
• High‑Temperature Long Life — Qualified for 5000 hours of ripple current application at 105°C, supporting demanding thermal environments.
• Snap‑In Radial Can — Snap‑in terminal mounting provides secure board attachment for power modules and chassis assemblies; package dimension listed as φ30×25L (L: 2.5 × D: 3 cm).
• Ripple Current Capability — Rated ripple current of 1.6 A at 120 Hz and 1.84 A at 50 kHz, enabling effective AC ripple handling across common switching and line frequencies.
• Leakage & Dissipation — Leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) for 100 V is specified (max. 0.20), supporting predictable ESR behavior.
• Wide Operating Temperature — Rated for operation from –40°C to 105°C for compatibility with a broad range of industrial environments.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy buffering where 100 V rating and long life at 105°C ensure stable DC rail performance under continuous ripple load.
• Ballast Systems — Specified suitability for ballast applications, providing reliable capacitance and endurance in lighting and ballast power circuits.
• General‑Purpose Power Filtering — Use for smoothing, decoupling, and energy storage in assemblies that require a compact 1200 µF, 100 V electrolytic solution with robust mounting.

Unique Advantages

• Long Life Assurance: 5000 hours at 105°C under rated ripple current provides predictable aging and maintenance planning for industrial systems.
• High Voltage & High Capacitance: 100 V rating combined with 1200 µF capacitance enables reduced component count when higher energy storage is required.
• Secure Snap‑In Mounting: Radial, snap‑in can simplifies mechanical retention in power assemblies and improves vibration tolerance compared to loose leaded parts.
• Frequency Versatile Ripple Performance: Specified ripple current at both 120 Hz and 50 kHz lets designers evaluate performance across line and switching frequencies.
• Measured Electrical Limits: Clear leakage current and tan δ specifications (including I ≤ 3√CV after 5 minutes at 20°C) support reliable thermal and electrical system design margins.
• Regulatory Compliance: RoHS status supports deployment in regions and projects requiring restricted substance compliance.
