UPJ1C331MPD

The UPJ1C331MPD is a radial lead aluminum electrolytic capacitor from Nichicon’s UPJ series, offering a 330 µF capacitance at a 16 V rating in a φ8 × 15 mm can. It is a polarized, radial-lead component designed for general-purpose power electronics and is specifically suited for use in switching power supplies where low impedance and reliable ripple handling are required.

This part provides quantified performance for designers: a wide operating temperature range of −55°C to +105°C, a rated endurance of 3000 hours at 105°C (φ8 case), and defined low- and high-frequency ripple current capabilities for both 120 Hz and high-frequency applications.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 16 V and ±20% tolerance at 120 Hz, 20°C.
• Low Loss (tan δ) — Specified tan δ of 0.16 at 20°C, 120 Hz for 16 V parts, supporting predictable ESR-related performance.
• Ripple Current Handling — Rated low-frequency ripple current of 263.9 mA at 120 Hz and high-frequency ripple current of 455 mA at 200 kHz, enabling effective smoothing in both LF and HF domains.
• Leakage Current — Measured leakage current of 158.4 µA, useful for budgeting standby currents in power designs.
• High-Temperature Endurance — Life/endurance rated at 3000 hours at 105°C for φ8 case size, consistent with UPJ series long-life characteristics.
• Radial Lead Package — φ8 × 15 mm aluminum can with 3.5 mm lead spacing (±0.5 mm) and lead diameter 0.6 mm, suitable for through-hole PCB mounting and manual or automated insertion.
• Wide Operating Range — Operational from −55°C to +105°C for use across a variety of temperature conditions.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and defined ripple current ratings help maintain stable rails.
• Power Supply Decoupling — Local energy storage and decoupling on regulator outputs in consumer and industrial power electronics.
• General-Purpose Power Electronics — Applications requiring polarized electrolytic capacitance with proven endurance at elevated temperature.

Unique Advantages

• Designed for switching environments: Low impedance characteristics and specified ripple current at both 120 Hz and 200 kHz support filtering across common switching frequencies.
• Quantified endurance: 3000 hours at 105°C (φ8) gives designers a measurable reliability target for high-temperature applications.
• Compact radial can: φ8 × 15 mm package with 3.5 mm lead spacing provides a space-efficient solution for through-hole boards.
• Clear electrical parameters: Specified tan δ, leakage current, and capacitance tolerance enable predictable performance and easier system-level budgeting.
• Wide temperature capability: −55°C to +105°C rating supports designs exposed to broad environmental ranges.
• RoHS compliant: Meets regulatory requirements for lead-free assemblies.
