LKG1J332MESBAK

The LKG1J332MESBAK is an aluminum electrolytic capacitor from Nichicon's LKG series, configured with a snap‑in (radial can) terminal for secure board mounting. It delivers 3.3 mF (3300 µF) capacitance at a 63 V rating, and is designed with the series' focus on audio equipment performance in mind.

Key electrical and mechanical attributes include a rated voltage of 63 V, capacitance tolerance of ±20%, a polarized snap‑in package (φ30 × 30L, 3 × 3 cm), a ripple current rating at low frequency, and specified endurance at elevated temperature. Note: this part is listed as End Of Life.

Key Features

• Capacitance & Voltage – 3.3 mF (3300 µF) nominal capacitance with a 63 V rated voltage and ±20% tolerance, suitable for DC‑link and power filtering in 63 V systems.
• Audio‑focused Series Design – Part of Nichicon’s LKG series developed for audio equipment; the series documentation notes design emphasis for high‑fidelity audio applications.
• Ripple Current Capability – Rated ripple current of 2.7 A at 120 Hz (low frequency), supporting power supply smoothing and decoupling duties under moderate AC ripple conditions.
• Endurance at Elevated Temperature – Lifetime specified as 1000 hours at 85°C, with post‑test limits defined for capacitance change, tan δ, and leakage current per the series endurance specification.
• Leakage Current – Specified leakage current value of 1360 µA as provided in the product description.
• Mechanical & Mounting – Snap‑in terminal, radial can package (φ30 × 30L, 3 × 3 cm) for robust board retention and tray packing for handling.
• Operating Temperature Range – Rated for −40°C to +85°C operation, matching the series’ stated category temperature range.
• Compliance – RoHS compliant as indicated in the product information.

Typical Applications

• Audio power supply filtering – Bulk smoothing and decoupling in high‑fidelity amplifier and preamplifier power rails where the LKG series is specified for audio equipment.
• Power amplification modules – Energy reservoir and ripple suppression in power amp stages operating up to the part’s 63 V rating.
• Audio electronics OEMs – Use in consumer and professional audio devices that require audio‑focused capacitor characteristics and snap‑in mounting for assembly robustness.

Unique Advantages

• Audio‑oriented design – Belongs to the LKG series, which is described for high‑grade audio equipment; useful where manufacturer series intent matters to design decisions.
• High capacitance at elevated voltage – 3300 µF at 63 V provides substantial energy storage for 63 V power rails without increasing capacitor count.
• Measured ripple handling – 2.7 A ripple current rating at 120 Hz supports stable operation in low‑frequency power supply environments.
• Temperature endurance specification – Endurance characterized for 1000 hours at 85°C, enabling designers to evaluate lifetime behavior under defined stress conditions.
• Robust mounting – Snap‑in radial can format simplifies assembly and mechanical retention on PCBs for through‑hole audio equipment builds.
• Regulatory compliance – RoHS compliant to support environmental requirements in many equipment designs.
