Electrical Characteristics Test Conditions:

  • Inductance (L): Tested at 100KHz/1V
  • Rated Current: Current at which temperature rises approximately 40°C at 25°C ambient temperature.
  • Saturation Current: Current at which inductance drops to about 30% of initial value upon instantaneous current application.
  • Maximum operating temperature (including self-heating) should not exceed 125°C.

Mechanical & Environmental Tests:

  • Solder Heat Resistance: Inductors should have no electrical or mechanical damage. Inductance change within ±10%. Preheating: 150°C 100s Max. Solder Temp: 255±5°C. Dip Time: 10s Max.
  • Vibration Test: Amplitude: 1.5 mm. Frequency: 10-55-10Hz / 1 MIN. Direction: X, Y, Z. Time: 2 HRS/X, Y, Z.
  • Shock Test: Dropped 10 times from 1m height onto a wooden board.
  • Solderability Test: Over 90% of electrode covered with solder. Preheating: 150°C 120s. Soldering Temp: 255±5°C. Time: 10s Max.
  • Temperature Characteristic: Appearance: No damage. Inductance change within ±10% of initial value. Range: -45°C ~ +125°C.
  • Humidity Test: 60°C±2°C / 96±2 Hrs. RH: 90-95%RH.
  • Low Temperature Storage: -45°C±2°C / 24Hrs.
  • Thermal Shock Test: -45±2°C for 30 min, +85±2°C for 30 min. 100 cycles.
  • High Temperature Storage: 85°C±2°C / 24Hrs.

Packaging:

  • 13-inch Reel: 3000pcs/reel.
  • Inner Box: 9000pcs/box.
  • Outer Box: 27000pcs/carton.
  • Reel Dimensions (P/W/A0/B0/K0/A/B/C/D/G/N/T): 8.0±0.1 / 16.0±0.3 / 5.4±0.2 / 5.9±0.2 / 2.2±0.15 / 330 / 21 / 13 / 16 / 17 / 100 / 20
  • Peel Strength: 20~140g.

Points For Attention:

  • Best shelf life: within 180 days from ex-factory date.
  • Seal unused products after opening to prevent oxidation.
  • Avoid contact with water, sweat, or dust on pads.
  • Re-test if used in different applications than intended.
  • Excessive voltage, current, or temperature can cause irreversible damage.
  • Not suitable for humid, dark, or strongly corrosive environments.
