MS21209 Datasheet Spec – Heli-Coil Screw Thread

Part Number : MS21209, NAMS21209

Function : Insert, Screw Thread, Coare and Fine, Screw Locking, Helical Coil, Cres





Heli-Coil inserts are precision formed screw thread coils worked into a diamond shape. The resultant surface finish is a mirror-like 8-16 micro inches. This wire is then wound into a spiral coil which when installed into Heli-Coil tapped holes, provides permanent conventional 60Âș internal screw threads. This assembled insert accommodates any standard bolt or screw (MIL-S-7742) and MIL-S-8879 (UNJ controlled radius root) male threaded members. (See page 8 for material availability.)

RT9168 datasheet

Description :

The RT9168/A is a 200mA/500mA low dropout and micropower regulator suitable for portable applications. The output voltages range from 1.5V to 5.0V in 100mV ncrements and 2% accuracy. The RT9168/A is designed or use with very low ESR capacitors. The output remains stable even with a 1μF ceramic output capacitor.

The RT9168/A uses an internal PMOS as the pass device, which does not cause extra GND current in heavy load and dropout conditions. The shutdown mode of nearly zero operation current makes the IC suitable for battery powered devices. Other features include current limiting and over temperature protection. The SOT-23-5 and SOP-8 packages are also available for larger power dissipation and design flexibility.
