UPJ2A270MPD

The UPJ2A270MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized can type with 27 µF capacitance and a 100 V rated voltage, specifically designed for applications that require low impedance and dependable performance in compact packages.

Targeted at switching power supplies and general-purpose power filtering, this part offers long-term endurance at elevated temperatures, controlled dissipation factor, and measurable ripple-current capability suitable for many power-electronics designs.

Key Features

• Rated capacitance and voltage — 27 µF at 100 V, with capacitance tolerance of -20% to +20% for predictable bulk energy storage and decoupling.
• Low impedance characteristics — UPJ series design emphasizes low impedance for switching power supply use; specified tangent of loss angle (tanδ) is 0.08 at 20°C, 120 Hz for the 63–100 V range.
• Temperature and endurance — Operating temperature range from -55°C to +105°C and rated endurance of 3000 hours at +105°C for the φ8 case size.
• Ripple-current capability — Low-frequency ripple current of 73 mA at 120 Hz and high-frequency ripple current of 146 mA at 200 kHz, documented for design verification.
• Low leakage — Specified leakage current of 81 µA after rated voltage application, supporting low-standby-loss designs.
• Compact radial package — φ8 × 15 mm can with 3.5 mm lead spacing (±0.5 mm) and radial leads for through-hole mounting and straightforward board placement.
• RoHS compliant and production-ready — Listed as RoHS compliant and in mass production; available in bulk/bag packing (no terminal forming) for volume assembly.

Typical Applications

• Switching power supplies — Low impedance and specified ripple-current ratings make this capacitor suitable for input/output filtering and energy buffering in SMPS designs.
• Power conversion and regulation — Useful for DC–DC converters and linear regulators where a compact 100 V, 27 µF polarized capacitor is required for stability and smoothing.
• General-purpose power filtering — Fits general-purpose roles in industrial and embedded power circuits needing reliable bulk capacitance in a small radial can.

Unique Advantages

• Designed for low impedance operation — The UPJ series specification calls out low impedance performance, helping reduce ripple and voltage drop in switching environments.
• High-temperature endurance — Rated for 3000 hours at +105°C (φ8), enabling sustained operation in thermally demanding applications.
• Measurable ripple handling — Explicit low- and high-frequency ripple-current specifications (73 mA @ 120 Hz, 146 mA @ 200 kHz) allow accurate thermal and reliability assessments.
• Compact, through-hole form factor — φ8 × 15 mm radial can with 3.5 mm lead spacing provides a small footprint for space-constrained boards while keeping assembly straightforward.
• Controlled electrical characteristics — Specified tanδ (0.08 at 20°C, 120 Hz) and leakage current (81 µA) support predictable AC and DC behavior in circuit simulations and designs.
• Production availability — Mass production status and standard bulk/bag packing simplify procurement and inventory planning.
