UPJ0J181MED

The UPJ0J181MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, offering 180 µF capacitance at a 6.3 V rating. It is a polarized, radial-can device designed for general-purpose power filtering and decoupling tasks where low impedance and reliable operation across a wide temperature range are required.

Part of the UPJ series—which is characterized as low impedance and suitable for switching power supplies—this specific part provides defined electrical performance, compact φ6.3×11L packaging with 2.5 mm lead spacing, and RoHS compliance.

Key Features

• Capacitance & Voltage: 180 µF rated at 6.3 V with ±20% tolerance to support bulk decoupling and smoothing in low-voltage power rails.
• Low Loss Characteristics: Specified tangent of loss angle (tan δ) of 0.22 at 6.3 V for predictable dissipation behavior in power circuits.
• Leakage Current: Measured leakage current of 34.02 µA, specified per the product data for initial condition verification.
• Ripple Current Ratings: 94.5 mA at 120 Hz and 175 mA at 200 kHz to accommodate ripple handling across common power-supply frequencies.
• Temperature Range: Rated for operation from −55°C to +105°C to cover a broad range of ambient conditions.
• Endurance: Specified 2000 hours life at 105°C as indicated for this part.
• Package & Mounting: Radial, can-style package (φ6.3×11L) with 2.5 mm lead spacing; shipped in bulk with no terminal forming.
• Environmental Compliance: RoHS compliant.
• Product Status: End of Life.

Typical Applications

• Switching power supplies: Low impedance characteristics make the UPJ0J181MED suitable for output smoothing and bulk decoupling in switching regulators.
• General-purpose power filtering: Use for decoupling and smoothing on low-voltage power rails in consumer and industrial electronics.
• Through-hole assemblies and prototyping: Radial-lead can packaging with 2.5 mm lead spacing is convenient for prototyping and through-hole PCBs.

Unique Advantages

• Series-level low-impedance design: The UPJ series is specified as low impedance and targeted at switching power supply applications, providing stable performance for power filtering.
• Measurable electrical performance: Clear specifications for tan δ (0.22), leakage current (34.02 µA), and ripple current at both 120 Hz and 200 kHz enable predictable thermal and electrical design margins.
• Wide operating temperature span: −55°C to +105°C rating supports deployment across varied ambient conditions.
• Compact radial-can footprint: φ6.3×11L package with 2.5 mm lead spacing fits space-constrained through-hole designs while maintaining required capacitance.
• RoHS compliant: Meets environmental regulatory requirements for lead-free assemblies.
