This nickel-plated brass adapter sleeve converts a 0.125 in. (3.17mm) shaft potentiometer to ¼" shaft (6.35mm), allowing for ¼" knobs to be used on a wider range of potentiometers. The cutout on the sleeve allows the set screw of the knob to secure directly to the shaft of the pot. Depending on the knob used, a longer set screw can be required.

Low-profile adhesive standoffs with a 0.180" standoff height that securely attaches your PCB to a flat surface. The post inserts into a 0.125” mounting hole and includes a locking tab that secures the PCB when inserted. It can be used with 1/16” or 1/32” thick PCBs. The 0.6 x 0.6” square base is offset to allow the base to be underneath the board when the mounting hole is close to the PCB edge and the offset base provides a large sticking surface while permitting the PCB to be mounted in tight spaces or close to walls. This can be useful when working with small enclosures. High-quality 3M™ brand double-sided tape secures the standoff to a flat surface. These standoffs are available in packs of 8, 24, or 100 pieces Features:

• Low profile 0.180" standoff height.
• Offset base allows use when holes are close to the PCB edge.

TC1044 charge pump voltage converter in an 8 pin DIP package. The TC1044S is a pin-compatible upgrade to the Industry standard TC7660 charge pump voltage converter. It converts a +1.5V to +12V input to a corresponding –1.5V to –12V output using only two low cost capacitors, eliminating inductors and their associated cost, size and EMI. Added features include an extended supply range to 12V, and a frequency boost pin for higher operating frequency, allowing the use of smaller external capacitors. The on-board oscillator operates at a nominal frequency of 10kHz. Frequency is increased to 45kHz when pin 1 is connected to V+.
