LAQ2P271MELZ35

The LAQ2P271MELZ35 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series designed for general-purpose electronic applications. It provides 270 µF capacitance at a 220 V rated voltage in a compact radial, can-type snap-in package optimized for board-mounted power circuits.

Key value is practical high-temperature endurance and measurable ripple handling: the part is specified for operation from −25 °C to +105 °C with a 2000-hour endurance at 105 °C, making it suitable where elevated ambient temperature and sustained DC bias with ripple are expected.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at 220 V rated voltage with ±20% tolerance (120 Hz, 20 °C), providing bulk capacitance for power circuits.
• High‑temperature Endurance — Rated for operation to +105 °C and specified for 2000 hours endurance at 105 °C under DC bias plus rated ripple current, with post-test limits on capacitance, tan δ, and leakage current.
• Snap‑in Mounting — Radial, can-type snap-in package for secure board insertion and mechanical retention in through‑hole assemblies.
• Ripple Current Capability — Rated ripple current handling of 1 A at 120 Hz and 1.2 A at 10 kHz supports smoothing and decoupling under AC ripple conditions.
• Electrical Loss & Leakage — tan δ ≤ 0.20 (120 Hz, 20 °C) and leakage current specified as I ≤ 3√C µA after 5 minutes at rated voltage (measurement basis provided in datasheet).
• Low‑temperature Stability — Impedance increases are specified for low temperature: |Z| at −25 °C may be up to 8× the value at +20 °C (measured at 120 Hz), enabling predictable performance across the rated temperature range.
• Safety Features — Pressure relief vent design is specified to operate without dangerous conditions (no flames or dispersion) under abnormal voltage test conditions defined in the series specifications.
• Compact Physical Size — Physical footprint L: 3.5 cm × D: 2.2 cm in a smaller-sized can for space-conscious board designs.

Typical Applications

• General-purpose power filtering — Bulk capacitance and rated ripple current make this part suitable for smoothing and energy storage in general-purpose power modules and supplies.
• Industrial and commercial electronics — The +105 °C temperature rating and 2000-hour endurance support sustained operation in elevated-temperature equipment environments.
• Board-mounted power systems — Snap-in radial can mounting provides secure mechanical retention for through‑hole assemblies requiring reliable bulk capacitance.

Unique Advantages

• High-temperature, long-duration endurance: Specified 2000 hours at 105 °C under DC bias plus rated ripple current, with defined limits for capacitance, tan δ and leakage current—allowing predictable aging characteristics.
• Measurable leakage and loss criteria: Leakage current and tan δ limits are specified (I ≤ 3√C µA; tan δ ≤ 0.20 at 120 Hz, 20 °C) to help designers budget for standby and loss parameters.
• Snap-in mounting for robust installation: Radial can snap-in terminals ensure firm board retention in through‑hole assemblies, aiding mechanical reliability during handling and operation.
• Defined low-temperature behavior: Impedance ratio specifications up to 8× at −25 °C (relative to +20 °C at 120 Hz) provide predictable performance when designing for cold-start or low‑temperature operation.
• Safety-focused construction: Series-level pressure relief venting is specified to avoid hazardous failure modes during abnormal-voltage testing, supporting safer system-level behavior.
• Compact footprint for space-constrained designs: The smaller-sized 3.5 cm × 2.2 cm can offers substantial capacitance in a reduced board area.
