UCA2V6R8MPD

The UCA2V6R8MPD is a miniature aluminum electrolytic capacitor from Nichicon's UCA series, provided in a radial-lead can package for through-hole mounting. It delivers a 6.8 µF capacitance at a 350 V rating, optimized for general-purpose power applications such as power supplies and ballasts.

Engineered for elevated-temperature operation, this part is specified to operate from −25 °C to +105 °C and is rated for 10,000 hours at 105 °C, offering a compact high-voltage solution with measurable ripple-handling capability across low and high frequencies.

Key Features

• Capacitance & Voltage — 6.8 µF nominal capacitance with a 350 V rated voltage for high-voltage decoupling and energy storage.
• Package & Mounting — Radial lead, can-style package with 5.0 mm lead spacing, designed for straightforward through-hole installation.
• Compact Dimensions — Small footprint with dimensions L: 1.6 × D: 1.0 cm, suitable where PCB space is limited.
• Operating Temperature & Lifetime — Rated for −25 °C to +105 °C with a specified life of 10,000 hours at 105 °C.
• High Ripple Current — Rated ripple handling of 110 mA at 120 Hz and 220 mA at 100 kHz, with frequency coefficients provided for other frequencies.
• Leakage Current Specification — Leakage current limit defined by datasheet formula: I ≤ 0.04CV + 100 (µA) after 1 minute at 20 °C.
• Tolerance & Polarity — Capacitance tolerance ±20% and polarized device; observe correct polarity in circuit installation.
• Regulatory — RoHS compliant.

Typical Applications

• Power Supplies — Bulk filtering and smoothing on high-voltage rails where a compact 350 V capacitor is required.
• Ballasts & Lighting Circuits — Voltage stabilization and ripple reduction in ballast and lamp-driver designs.
• Industrial Control — General-purpose decoupling and energy storage for control electronics operating at elevated voltages and temperatures.

Unique Advantages

• Compact high-voltage solution: 6.8 µF at 350 V in a small radial-can package reduces PCB area compared with larger packages for similar voltage ratings.
• Designed for elevated-temperature duty: Specified for operation to +105 °C and a 10,000-hour rated life at that temperature for reliable long-term performance.
• Measurable ripple capability: Explicit ripple ratings at 120 Hz and 100 kHz let designers size parts accurately for both low- and high-frequency applications.
• Clear leakage specification: Leakage current bounded by a standard datasheet formula (0.04CV + 100 µA) to support predictable bias behavior after start-up.
• Through-hole convenience: Radial lead, can package with 5 mm lead spacing simplifies assembly and replacement in legacy and repair-prone designs.
• RoHS compliance: Meets environmental requirements for lead-free assemblies.
