ELJPA101KF – PANASONIC

Overview

The Panasonic ELJ-PA101KF is a 100 µH unshielded wirewound drum core inductor designed for robust performance in signal processing applications. Its critical operational characteristic is the precise inductance value maintained across varying current levels, crucial for predictable circuit behavior. A key design consideration for this component is the trade-off between its relatively high DC resistance (5Ω max) and its compact 1210 package size; engineers must balance the need for low power loss against board space constraints, especially in battery-powered or thermally sensitive designs.

Key Features

• Inductance: 100 µH ±10%
• Current Rating: 90 mA
• DC Resistance (DCR): 5Ω Max
• Q Factor: 20 @ 796 kHz
• Self-Resonant Frequency: 6.5 MHz
• Package: 1210 (3225 Metric) – 3.20mm x 2.50mm x 2.40mm
