Core material Ferrite

Terminations Leads: RoHS compliant tin-silver over copper

Base pad: RoHS compliant gold over nickel over phos bronze

Other terminations available at additional cost.

Weight SER2915L–28.5g; SER2915H–29.7g; SER2918H–35.7 g

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.

Tray 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 25 pieces per tray

PCB washing Tested to MIL-STD-202 Method 215 plus an additional

aqueous wash. See Doc787_PCB_Washing.pdf.

• Same electrical specifications as Coilcraft’s SER2800

• Extremely low DCR; Current handling to >100 Amps

• Third mounting pad for greater stability and board adhesion

1. When ordering, specify

termination code:

SER2915-333KL

Termination: L = RoHS compliant tin-silver

over copper.

Special order:

T = RoHS tin-silver-copper

(95.5/4/0.5) or

S = non-RoHS tin-lead

(63/37).

2. Inductance measured at 500 kHz, 0.1 Vrms,

0 Adc on an Agilent/HP 4284A LCR meter or

equivalent.

3. DCR measured on a Keithley 580 micro-

ohmmeter or equivalent.

4. SRF measured using an Agilent/HP 4395A

network analyzer and an Agilent/HP 16092A

test fixture.

5. Peak dc current at which the inductance

drops the specified amount from its value

without current. When

Isat rating is less than

Irms, Isat is the more critical specification.

6. Current that causes the specified tempera-

ture rise from 25°C ambient. When

Irms is

greater than

Isat, Isat is the more critical

specification, and

See Temperature Rise vs Current curve on

next page.

7. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount

Components” before soldering.
