Sd12 Nominal inductance

Product catalog summary

Specifications:
The document outlines the specifications for Sd12 nominal inductance chokes. These are used for decoupling in circuits, spark suppression, and as storage chokes in switched-mode power supplies, particularly in automotive electronics for safety circuits up to 6 A. The inductance range is from 10 μH to 15 mH with a tolerance of ±10%, and tighter tolerances are available upon request. The operating temperature range is -25°C to +125°C.

Procedures:
Solderability is compliant with DIN IEC 68-2-20 Ta at 235°C for 5 seconds, and resistance to soldering heat is compliant with DIN IEC 68-2-20 Tb at 260°C for 5 seconds. Packaging is done in trays with a packaging size of 50 pieces per layer.

Design and Construction:
Inductances up to 680 µH have wire terminations that act as pins for assembly, while inductances above 680 µH have integral pins and can be supplied with or without a flame-retardant plastic cap according to UL 94-VO.

Performance Parameters:
Inductance is measured at +23°C with 50 mV across the inductor. Self-resonant frequency figures are typical values. The maximum current rating is specified for an ambient temperature of 40°C, with adjustments required for different temperatures as per diagrams on page 2.06.

Data Summary:
The document includes tables listing various inductance values, their corresponding frequencies, resistances, maximum currents, and part numbers, both with and without caps.

Anwendung Entkopplung in Schaltungen im NF-Bereich, Funkentstörung, Einsatz als Speicherdrossel bis ca. 180 µWs in getakteten Netzteilen, in der Kfz-Elektronik für Sicherheitsschaltkreise bis 6 A usw.. Application Decoupling of high and low frequency circuits, etc. We recommend these Chokes for a pplication in telecommunication, video e quipment and electronic data processing systems. Bis einschließlich 680 μH werden die Wickeldraht enden durch den Sockel herausgeführt und bilden so die Anschlüsse für die Drossel (Fig. 1). Die Drosseln Sd 12 haben oberhalb von 680 µH Anschlussstifte (Fig. 2), sie können mit und ohne Kunststoffhaube geliefert werden. Die Haube ist f lammhemmend eingestellt nach UL 94 - V0.
