UPT2D681MRD

The UPT2D681MRD is an aluminum electrolytic capacitor in a radial-can package designed for high ripple current applications. It delivers 680 µF nominal capacitance at a 200 V rating with polarized radial leads for through-hole mounting.

Targeted at ballast applications and general-purpose electronic equipment, this capacitor combines elevated ripple-current capability with long-life endurance and RoHS compliance to meet demanding operating environments between –40°C and +105°C.

Key Features

• Electrical Performance: 680 µF nominal capacitance with ±20% tolerance and a 200 V rated voltage; polarized design suitable for DC filtering and energy storage in through-hole assemblies.
• Ripple & Frequency Performance: Rated ripple current performance of 1.5 A at 120 Hz and 2.4 A at 10 kHz; frequency coefficient increases allowable ripple (coefficient 1.60 at ≥10 kHz) to support higher-frequency applications.
• Reliability & Long Life: Endurance rated for 5,000 hours at 105°C under DC bias plus rated ripple current, with capacitance change within ±20% and leakage current meeting specified limits after endurance testing.
• Package & Mounting: Radial lead, can-style package with 1.0 cm lead spacing and compact footprint (L: 5 × D: 2.2 cm) for straightforward through-hole placement and secure mechanical mounting.
• Thermal Range & Stability: Operating temperature range from –40°C to +105°C; specified impedance and tan δ limits for stable performance across the operating range (tan δ ≤ 0.12 at 200 V, 120 Hz, 20°C).
• Environmental Compliance: RoHS compliant, supporting restricted-substance requirements for modern electronic assemblies.

Typical Applications

• Lighting ballasts: Suited for ballast applications where elevated ripple-current handling is required.
• General-purpose electronic equipment: Used in a variety of general-purpose circuits requiring bulk capacitance and reliable DC performance.
• High-ripple current circuits: Appropriate for circuits that demand sustained ripple current capability over long operating periods.

Unique Advantages

• Designed for elevated ripple loads: Specified ripple currents of 1.5 A (120 Hz) and 2.4 A (10 kHz) provide clear, verifiable limits for design and thermal planning.
• Long-term thermal endurance: 5,000 hours rated life at 105°C under rated conditions helps ensure longevity in high-temperature deployments.
• Compact radial-can form factor: Small L × D footprint and 1.0 cm lead spacing make it easy to integrate into through-hole power assemblies without sacrificing performance.
• Stable electrical characteristics: Defined tan δ and leakage-current specifications allow predictable behavior after application of rated voltage and during lifecycle testing.
• Regulatory compliance: RoHS status provides environmental compliance for regulated product lines and manufacturing processes.
