UPJ2A100MED

The UPJ2A100MED is a radial-lead aluminum electrolytic capacitor from Nichicon designed for power-filtering and decoupling in general-purpose electronic equipment. It is a polarized aluminum electrolytic can optimized for switching power supplies, offering low impedance and rated for operation up to 105°C.

Key characteristics include a 100 V rated voltage, 10 µF capacitance with ±20% tolerance, and a compact radial package suited to densely packed power assemblies that require stable performance at elevated temperatures.

Key Features

• Electrical performance — Rated 100 V with 10 µF capacitance and ±20% tolerance, providing predictable decoupling performance for DC rails.
• Low impedance for power applications — Specified as a low-impedance UPJ series part and supplied with measured ripple current figures: 26 mA at 120 Hz and 52 mA at 200 kHz for effective ripple handling in switching environments.
• High-temperature operation — Operating range of -55°C to +105°C with a specified load life of 2000 hours at +105°C, supporting sustained use in warm operating conditions.
• Radial lead, compact package — Radial can package with lead spacing of 2.5 mm and physical size L: 1.1 × D: 0.63 cm, useful where through-hole mounting and serviceability are preferred.
• Polarized design — Standard polarized electrolyte construction for higher capacitance density in power-supply smoothing and bulk decoupling applications.
• RoHS compliant — Meets RoHS requirements as provided in the product information.

Typical Applications

• Switching power supplies — Low impedance and specified ripple-current figures make this capacitor suitable for output filtering and bulk decoupling in switch-mode power supplies.
• General-purpose power filtering — Polarized aluminum electrolytic in a compact radial can for smoothing and reservoir functions across a variety of electronic equipment.
• DC rail decoupling — Use on DC power rails where a 100 V rating and 10 µF capacitance are required for transient suppression and stability.

Unique Advantages

• High-voltage capability: 100 V rating enables use on higher-voltage rails without series stacking or additional components.
• Thermal endurance: Rated for operation to +105°C with a 2000-hour load-life specification at that temperature for predictable performance in warm environments.
• Measurable ripple handling: Published ripple-current values at 120 Hz and 200 kHz help designers match capacitor selection to switching-frequency and low-frequency ripple requirements.
• Compact, serviceable form: Radial-lead can with small footprint and 2.5 mm lead spacing for through-hole assembly and straightforward replacement or prototyping.
• Compliance-ready: RoHS compliance supports deployments where restricted-substance conformance is required.
