UKT1H101MPD

The UKT1H101MPD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UKT series designed for general audio equipment and applications requiring a wide temperature range. This polarized can-style capacitor delivers 100 µF at a 50 V rating with a compact φ8 × 11.5 mm case size and 3.5 mm lead spacing.

Engineered for reliability across extended temperature extremes, the part provides controlled dissipation factor, defined ripple-current capability at low and high frequencies, and a 1000-hour endurance at 105°C—attributes suitable for demanding audio and related electronic power applications.

Key Features

• Capacitance & Voltage: 100 µF rated capacitance at 50 V nominal—sized for power filtering and energy storage in compact radial configurations.
• Wide Temperature Range: Specified for −55°C to +105°C operation, supporting designs that must tolerate low ambient cold and elevated operating temperatures.
• Endurance: 1000 hours at 105°C endurance rating, with specified limits on capacitance change, tan δ and leakage current after the test.
• Low Loss (tan δ): tan δ specified at 0.14 (measured at 20°C, 120 Hz for 50 V), indicating controlled ESR-related losses for audio-frequency performance.
• Ripple Current Capability: Low-frequency ripple current 190 mA (120 Hz) and high-frequency ripple current 285 mA (10 kHz), with frequency coefficients defined in the series datasheet.
• Leakage Current: Leakage current specified at 150 µA (measurement conditions per product data), providing predictable quiescent behavior.
• Package & Mounting: Radial-lead, can-style package with φ8 × 11.5 mm dimensions and 3.5 mm lead spacing (±0.5 mm), available in bulk or bag packing with no terminal forming.
• Compliance & Qualification: AEC-Q200 listed in product specifications and RoHS compliance stated in the series datasheet.

Typical Applications

• Audio Equipment: Suited for general audio equipment where stable capacitance, wide temperature tolerance, and defined loss characteristics are required.
• Power Supply Filtering: Used in compact power-supply sections for smoothing and decoupling where space and ripple handling are constrained.
• Embedded Electronics: Fits small-form-factor boards needing a radial electrolytic with predictable endurance and leakage performance.

Unique Advantages

• Temperature-resilient operation: −55°C to +105°C rating supports a broad range of environmental conditions and thermal margins in system design.
• Documented endurance: 1000-hour rating at 105°C gives designers a measurable lifetime parameter for reliability planning.
• Frequency-aware ripple performance: Specified ripple currents at 120 Hz and 10 kHz (with series frequency coefficients) help size the capacitor for both low- and high-frequency ripple scenarios.
• Compact radial form factor: φ8 × 11.5 mm can with 3.5 mm lead spacing enables high-density board layouts while preserving robust lead-mounted connections.
• Controlled loss and leakage: tan δ = 0.14 (50 V, 120 Hz) and 150 µA leakage provide predictable electrical behavior important for audio and power applications.
• Production-ready availability: Listed as mass production and offered in bulk/bag packing to support volume assembly and inventory planning.
