LLG2Z681MELA25

The LLG2Z681MELA25 is a snap‑in terminal type aluminum electrolytic capacitor from Nichicon’s LLG series, designed as a one‑rank smaller case size than the LLS series to support equipment downsizing. It is a polarized, general‑purpose capacitor rated for 680 µF at 180 V and is RoHS compliant.

Engineered for compact power designs, this component provides high capacitance in a reduced footprint with specified endurance, ripple capability, and a practical operating temperature range for a wide range of general‑purpose applications.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 180 V for bulk energy storage and smoothing in power circuits.
• Compact Snap‑in Package — Radial, can snap‑in mounting simplifies board retention and assembly while enabling smaller equipment designs; case dimension: L: 2.5 × D: 2.5 cm.
• Temperature Range — Specified operating range of −40 °C to +85 °C (for the 160–250 V category), supporting typical ambient conditions for general‑purpose electronics.
• Endurance — Rated for 2000 hours at 85 °C under DC bias plus rated ripple current; after the test the capacitor meets capacitance, loss, and leakage requirements specified in the datasheet.
• Ripple Current Capability — Rated ripple current of 2.1 A at 120 Hz and 3.15 A at 100 kHz for handling AC ripple in power supply applications.
• Leakage Current Specification — Leakage defined by I ≤ 3√(C·V) µA after 5 minutes at 20 °C, enabling predictable standby and leakage behavior.
• Electrical Stability — Low‑temperature impedance characteristics and tan δ limits are specified (tan δ max. 0.15 for the 160–400 V range at 120 Hz, 20 °C), supporting predictable AC performance.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and decoupling in power supplies where a high capacitance, snap‑in aluminum electrolytic is required.
• Compact equipment designs — Suited for applications that benefit from a one‑rank smaller case size to reduce PCB area and enclosure volume.
• Industrial and consumer electronics — General‑purpose use where the specified voltage, temperature range, and endurance meet product requirements.

Unique Advantages

• Smaller case size for downsizing: One rank smaller than the LLS series to help reduce overall equipment footprint.
• Snap‑in mounting: Secure board retention and straightforward assembly in radial can format.
• Specified ripple and endurance: Defined ripple current ratings at 120 Hz and 100 kHz plus 2000‑hour endurance at 85 °C provide measurable performance for power applications.
• Predictable leakage behavior: Leakage current defined by a clear formula (I ≤ 3√CV), enabling accurate power‑budget calculations.
• Wide usable temperature range: −40 °C to +85 °C operation for the 160–250 V category supports a variety of environmental conditions.
• Regulatory compliance: RoHS conformity aids in meeting environmental and regulatory requirements.
