1 / 5 page Applications • Voltage Regulator Module (VRM) • Multi-phase regulators • Desktop and server VRMs and EVRDs • Data networking and storage systems • Notebook regulators • Point-of-load modules • Base station equipment • Battery power systems • Graphics cards Environmental Data • Storage temperature range: -55°C to +125°C • Operating temperature range: -55°C to +125°C (ambient plus self temperature rise) • Solder reflow temperature: J-STD-020D compliant Packaging • Supplied in tape and reel packaging, 400 parts per 13” reel Description • Halogen free • 125°C maximum total operating temperature • 13.8x 12.5 x 5.0mm maximum surface mount package • Powder Iron core material • Magnetically shielded, low EMI • High current carrying capacity, low core losses • Inductance range 0.22µH to 2.2µH • Current range from 20 to 110 Amps • Frequency range up to 5MHz • RoHS compliant High Current Power Inductors HCM1305 Series 1010 BU-SB101160 Page 1 of 4 Data Sheet: 4371 SMD Device 1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.25Vrms, 0.0Adc @ 25°C. 2. Full Load Inductance (FLL) Test Parameters: 100kHz, 0.25Vrms,Isat @ 25°C. 3. Irms: DC current for an approximate temperature rise of 40°C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width, air-flow and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the part not exceed 125°C under worst case operating conditions verified in the end application. 4. Isat: Peak current for approximately 20% rolloff at +25°C. 5. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI. Bp-p: (Gauss), K: (K-factor from table), L: (Inductance in μH), ΔI (Peak-to-peak ripple current in Amps). 6. Part Number Definition: HCM1305-xxx-R - HCM1305 = Product code and size - xxx= Inductance value in μH, R = decimal point - “-R” suffix = RoHS compliant Product Specifications Part OCL 1 FLL 2 Min Irms 3 Isat 4 DCR (m Ω) DCR (m Ω) Number 6 ± 20% ( μH) ( μH) (Amps) @25°C (Amps) @20°C Nominal @20°C Maximum K-factor 5 HCM1305-R22-R 0.22 0.14 51 110 0.63 0.72 367 HCM1305-R47-R 0.47 0.30 38 65 0.80 0.92 174 HCM1305-R56-R 0.56 0.36 36 55 1.15 1.33 110 HCM1305-R68-R 0.68 0.44 34 53 1.15 1.33 110 HCM1305-R82-R 0.82 0.52 31 52 1.40 1.61 140 HCM1305-1R0-R 1.00 0.64 29 50 2.10 2.42 117 HCM1305-1R5-R 1.50 0.96 23 48 2.75 3.16 120 HCM1305-2R2-R 2.20 1.41 20 32 4.60 5.29 110 Pb HALOGEN HF FREE Dimensions - mm |
