UPJ1H151MPD

The UPJ1H151MPD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPJ series designed for low-impedance power applications. It delivers 150 µF at 50 V with a compact φ10 × 20 mm can and 5 mm lead spacing.

Engineered for switching power supplies and general-purpose power filtering, this part combines low loss (tanδ 0.10), controlled leakage, and long load life at elevated temperature for reliable performance in demanding electronic power stages.

Key Features

• Capacitance & Rated Voltage — 150 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance.
• Low Loss — tanδ 0.10 (specified for 50 V) to reduce dissipation in power applications.
• Leakage Current — Product-specified leakage current of 225 µA; datasheet basis defined as 0.03CV (µA) after 1 minute at 20°C.
• High Temperature Endurance — 5000 hours rated life at +105°C (specified for the φ10 case size) under DC bias plus rated ripple current.
• Ripple Handling — Ripple current capability: 307.8 mA at 120 Hz and 570 mA at 200 kHz, suitable for switching regulator output filtering.
• Operating Range — Wide operating temperature range from −55°C to +105°C for robust performance across environments.
• Package & Mounting — Radial-lead can (φ10 × 20 mm) with 5 mm lead spacing; supplied Bulk (No Terminal Forming) / Bag packing for mass production use.
• Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance and specified ripple current make this capacitor suitable for output and bulk filtering in switch-mode power supplies.
• Industrial Power Electronics — Long load life at 105°C and broad temperature tolerance support stable filtering in industrial power stages.
• Consumer Power Rails — Compact radial can and low loss help maintain stable DC rails in consumer devices and power adapters.
• Telecom and Networking Power Modules — Ripple capability and endurance characteristics assist in maintaining regulation and reliability in power modules.

Unique Advantages

• Proven long-term endurance: 5000 hours at +105°C for the φ10 case provides predictable life performance under elevated temperature and bias.
• Low dissipation: tanδ 0.10 at 50 V reduces internal heating and improves efficiency in high-frequency power circuits.
• Effective ripple suppression: Specified ripple currents at 120 Hz and 200 kHz demonstrate capability across low and high-frequency power environments.
• Compact radial package: φ10 × 20 mm can with 5 mm lead spacing delivers useful capacitance density for space-constrained boards.
• Controlled leakage behavior: Product leakage specification (225 µA) and datasheet leakage formula (0.03CV) provide clear expectations for bias performance.
• RoHS compliant supply: Conforms to RoHS directive for environmentally restricted substance requirements.
