UPJ1J151MPD

The UPJ1J151MPD is an aluminum electrolytic capacitor engineered for low-impedance power applications. It is a polarized, radial-lead radial-can type capacitor rated at 150 µF and 63 V with a capacitance tolerance of ±20%.

Designed for switching power supplies and general-purpose power filtering, this Nichicon UPJ-series device delivers reliable performance across a wide temperature range (−55°C to +105°C) and is RoHS compliant. It provides endurance under extended elevated-temperature load conditions as specified by the series.

Key Features

• Rated Capacitance & Voltage — 150 µF at 63 V with ±20% tolerance for bulk energy storage and smoothing on 63 V rails.
• Low Impedance Design — Engineered for low impedance to support switching power supply applications and reduce ripple-related losses.
• High-Temperature Endurance — Rated for operation from −55°C to +105°C with load-life endurance specified (5000 hours at +105°C for applicable case sizes).
• Ripple Current Capability — Supports 359.1 mA at 120 Hz and 665 mA at 200 kHz, enabling effective ripple handling across low and high-frequency domains.
• Mounting & Package — Radial lead, radial can package with 5 mm lead spacing for through-hole mounting and straightforward PCB integration.
• Polarized — Specified polarized capacitor for DC power applications where correct polarity is required.
• Environmental — RoHS compliant, meeting current restricted-substance requirements.

Typical Applications

• Switching Power Supplies — Low-impedance characteristics make it suitable for output filtering and energy storage in switch-mode regulators.
• Power Filtering & Decoupling — Bulk capacitance for smoothing supply rails and reducing voltage ripple in electronic systems.
• High-Temperature Electronics — Suitable for designs that operate in elevated ambient temperatures up to +105°C where sustained endurance is required.
