1. Please specify

termination and packaging codes:

SER1052-572MLD

Termination: L = RoHS compliant tin-silver over copper

(pins 1 and 2); matte tin over nickel over

phos bronze (pin 3).

Special order:

T = RoHS tin-silver-copper (95.5/4/0.5)

or

S = non-RoHS tin-lead (63/37).

Packaging: C = 7

″ machine-ready reel. EIA-481 em-

bossed plastic tape (200 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 em-

bossed plastic tape. Factory order only,

not stocked (700 parts per full reel)

2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an

Agilent/HP 4284A or equivalent.

3. DCR measured on a micro-ohmmeter.

4. SRF measured using an Agilent/HP 4395A network

analyzer and an Agilent/HP 16193A test fixture.

5. DC current at which the inductance drops the specified

amount from its value without current.

6. Current that causes the specified temperature rise from

25°C ambient.

7. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components”

before soldering.

Designer’s Kit C421 contains 3 of each value

Core and winding loss See www.coilcraft.com/coreloss

Core material Ferrite

Terminations RoHS compliant tin-silver over tin over nickel over phos

bronze (pins 1 and 2); matte tin over nickel over phos bronze (pin 3).

Other terminations available at additional cost.

Weight 1.6 g

Ambient temperature –40°C to +85°C with Irms current, +85°C to

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 200/7

″ reel; 700/13″ reel Plastic tape: 24 mm wide,

0.4 mm thick, 16 mm pocket spacing, 5.45 mm pocket depth
