UPS2D100MPD

The UPS2D100MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPS series. It is a miniature, low-impedance can-type capacitor designed for use in switching power supplies and general-purpose power filtering applications.

With a 100 µF capacitance at 100 V rated voltage, low loss (tanδ 0.08 at 20°C/120 Hz) and endurance specified at elevated temperature, this part targets compact power circuits that require reliable bulk energy storage and ripple suppression.

Key Features

• Electrical performance — 100 µF nominal capacitance with tolerance ±20%; rated at 100 V.
• Low dissipation factor — tanδ 0.08 (measured at 20°C, 120 Hz), supporting lower AC loss in filtering applications.
• Ripple current capability — Low-frequency ripple current: 300 mA; High-frequency ripple current: 420 mA, enabling effective smoothing of switching waveforms.
• Leakage current — Specified leakage current of 300 µA (measured at 20°C after 1 minute), suitable for power supply decoupling roles.
• Thermal and endurance rating — Operating range −40°C to +105°C with endurance specified for 2000 hours at 105°C, supporting sustained operation in elevated-temperature environments.
• Compact radial can package — Physical size φ12.5 × 20 mm with 5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies.
• Packaging options — Available in bulk (no terminal forming) or bag packing to suit prototyping and production handling.
• RoHS compliant — Conforms to RoHS environmental requirements as indicated in product data.

Typical Applications

• Switching power supplies — Output filtering and bulk energy storage in compact SMPS designs where low impedance and reliable ripple handling are required.
• General-purpose power filtering — Decoupling and smoothing in a variety of electronic power circuits that require a 100 µF/100 V radial electrolytic.
• Embedded power modules — Local energy storage and transient suppression in small power conversion modules and board-level regulators.

Unique Advantages

• Miniature, low-impedance construction — Delivers the damping and smoothing characteristics needed in switching supplies while occupying minimal board area (φ12.5 × 20 mm).
• High-voltage, mid-capacitance option — 100 V rating with 100 µF capacitance supports designs requiring higher DC bus voltages without sacrificing capacitance.
• Measured ripple performance — Specified low- and high-frequency ripple currents enable predictable behavior across switching and higher-frequency domains.
• Endurance at elevated temperature — Rated for 2000 hours at 105°C, providing design confidence for sustained operation in warm environments.
• Through-hole radial mounting — Simplifies prototyping and replacement in legacy or mixed-technology assemblies with standard 5 mm lead spacing.
• RoHS compliance — Meets environmental regulation requirements for restricted substances.
