1. When ordering, please specify packaging code:
EPL2014-103ML
C
Packaging: C =7
″ machine-ready reel. EIA-481 embossed plastic
tape (2000 parts per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter C instead.
D =13
″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (7500 parts per
full reel).
Designer’s Kit C413 contains 5 each of all values
Core material Ferrite
Terminations Since March, 2009: RoHS compliant tin-silver-copper
over tin over nickel over silver. Prior to March, 2009: RoHS compliant
tin-silver-copper over gold over nickel over silver.
Weight 20 – 25 mg
Ambient temperature –40°C to +85°C with
Irms current, +85°C to
+125°C with derated current
Storage temperature Component: –40°C to +125°C.
Packaging: –40°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging 2000/7
″ reel; 7500/13″ reel Plastic tape: 8 mm wide,
0.28 mm thick, 4 mm pocket spacing, 1.65 mm pocket depth
PCB washing Only pure water or alcohol recommended
• Miniature shielded power inductors; 2.0 × 2.0 mm footprint
• Extremely low DCR and very high SRF ratings
•
Isat ratings as high as 2.8 A
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 4395A network analyzer or equivalent.
5. DC current at which the inductance drops from its value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
