LAQ2P101MELZ20

The LAQ2P101MELZ20 is a Nichicon LAQ series aluminum electrolytic capacitor in a snap‑in terminal can, specified at 100 µF and 220 V. Designed for general‑purpose power applications, it combines a compact φ22 × 20 mm package with rated performance up to 105°C and defined ripple‑handling and leakage characteristics for reliable board‑level power conditioning.

This part is supplied in tray packing for mass production and is intended where a robust, board‑mounted electrolytic is required for smoothing, bulk decoupling or DC link applications within the capacitor’s defined electrical and environmental limits.

Key Features

• Voltage and Capacitance — Rated at 220 V and 100 µF with a tolerance of ±20% (measured at 120 Hz, 20°C), providing predictable energy storage for medium‑voltage power circuits.
• Snap‑in Terminal Package — Radial, can‑type snap‑in mounting simplifies PCB assembly and secures the capacitor for high‑vibration or high‑current environments.
• Compact Size — φ22 × 20 mm (D × L / 2.2 cm × 2.0 cm) offers a small footprint for space‑constrained power modules and assemblies.
• High Temperature Endurance — Rated operating temperature range of −25°C to +105°C with 2000 hours endurance at 105°C under DC bias plus rated ripple current, supporting elevated‑temperature operation.
• Ripple and Leakage Specs — Specified ripple current: 500 mA at 120 Hz (low frequency) and 600 mA at 10 kHz (high frequency); listed leakage current of 0.44 mA for controlled standby loss and predictable self‑discharge.
• Safety Feature — LAQ series includes a pressure relief vent designed to operate under abnormal conditions to reduce hazardous failure modes.
• Production Ready — Supplied in tray packing and designated for mass production, easing integration into manufacturing workflows.

Typical Applications

• General‑purpose power electronics — Bulk smoothing and decoupling in medium‑voltage DC circuits where 220 V rating and defined ripple capability are required.
• Industrial power modules — Board‑mounted energy storage and filtering in assemblies that demand compact, snap‑in capacitors with elevated‑temperature endurance.
• Power supply filtering — DC link and output filtering where stable capacitance, controlled leakage (0.44 mA), and ripple handling (500 mA / 600 mA) are important for performance.

Unique Advantages

• 220 V rating with compact footprint — Enables medium‑voltage designs without sacrificing board space thanks to the φ22 × 20 mm construction.
• Clear ripple specifications — Separate low‑ and high‑frequency ripple current ratings (500 mA at 120 Hz, 600 mA at 10 kHz) allow designers to match the part to expected operating waveforms.
• Elevated temperature reliability — 2000 hours endurance at 105°C under rated conditions supports reliable operation in warmer environments or thermally dense assemblies.
• Low standby leakage — 0.44 mA leakage current helps limit quiescent loss and improves predictability for power budgets and hold‑up calculations.
• Robust mounting — Snap‑in can package secures the capacitor to the PCB for mechanical stability and simplified assembly.
• Safety design elements — Series pressure relief vent reduces the risk of dangerous failures under abnormal conditions.
