Notes:
1) Open Circuit Inductance Test Parameters: 100kHz, 0.25Vrms, 0.0Adc
+/-20% except for LD1-330-R to LD1-331-R and LD2-470-R to LD2-471-R which is +/-10%
2) RMS current for an approximate ∆T of 40°C. It is recommended that the temperature of the
part not exceed 125°C
3) Peak current for an approximate 10% rolloff at 20°C
Applications
• Buck or boost inductor
• Noise filtering and output filter chokes
• Computers
• Power supplies
• Test equipment instrumentation
Environmental Data
• Storage temperature: -40°C to +125°C
• Operating temperature: -40°C to +125°C (range is application
specific). Temperature rise is approximately 40°C at rated rms
current.
• Solder reflow temperature: 260°C max. for 10 seconds max.
Packaging
• Supplied in tape and reel packaging, LD1 (2,000),
LD2 (1,000) parts per reel
