UPA0J122MPD3

The UPA0J122MPD3 is a Nichicon UPA series miniature aluminum electrolytic capacitor: a radial-lead, high-reliability component optimized for low impedance and high ripple-current performance. It delivers 1200 µF capacitance at a 6.3 V rating in a compact φ10 × 16 mm can with 5.0 mm lead spacing.

Designed for general-purpose power filtering and switching power supply applications, this part combines a wide operating temperature range (−55°C to +105°C) and long endurance (4,000 hours at 105°C) to support demanding embedded and industrial designs.

Key Features

• Capacitance & tolerance — 1.2 mF (1200 µF) with ±20% tolerance measured at 120 Hz, 20°C.
• Rated voltage — 6.3 V capability suitable for low-voltage power rails and smoothing applications.
• Low impedance — Specified impedance of 98 mΩ, enabling effective decoupling and transient response.
• Loss tangent (tan δ) — 0.22 maximum (120 Hz, 20°C) at the 6.3 V rating; suitable for capacitors above 1000 µF with applicable correction noted in the datasheet.
• High ripple-current handling — 1.054 A at 120 Hz (low frequency) and 1.24 A at 10 kHz (high frequency) for robust ripple dissipation in switching environments.
• Leakage current — 226.8 µA (measured condition as provided), supporting predictable power loss and standby behavior.
• Temperature and endurance — Operates from −55°C to +105°C with a rated lifetime of 4,000 hours at 105°C for the φ10 case size.
• Package and mounting — Radial lead, can-style case (φ10 × 16 mm), lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packaging.
• Regulatory status — RoHS compliant as provided in the product data.

Typical Applications

• Switching power supplies — Bulk and output filtering where low impedance and high ripple capability improve regulation and reduce voltage ripple.
• Power rail decoupling — Local energy storage and smoothing on low-voltage DC rails in embedded and industrial systems.
• Backup and hold-up circuits — Energy buffering and short-term hold-up in small power-management modules that require compact, reliable capacitors.

Unique Advantages

• Compact, high-capacitance package — 1200 µF in a φ10 × 16 mm can minimizes board area while delivering substantial bulk capacitance.
• Measured low impedance — 98 mΩ impedance improves transient response and reduces power-supply ripple without oversizing the capacitor.
• Certified ripple performance — Specified ripple current ratings at both 120 Hz and 10 kHz support designs across low and high frequency domains.
• Wide temperature tolerance and long life — −55°C to +105°C operation and a 4,000-hour endurance at 105°C provide predictable behavior in thermally demanding applications.
• Radial-lead convenience — 5.0 mm lead spacing and standard radial can format simplify through-hole assembly and repairable layouts.
• RoHS compliance — Material compliance supports regulatory requirements for modern electronic designs.
