Capacitor selection tips
In this article, we'll explore nine expert capacitor tips that will help you navigate the complexities of capacitor selection, application, and maintenance.
FAQs about Capacitor selection tips
What are the selection considerations of output capacitors?
This application note describes the selection considerations of output capacitors, based on load transient and output impedance of processors power rails. Presently, there are no specific tools available for non-Intel processor output capacitors selection in multiphase designs.
How to select capacitors?
Aside from the capacitance, another thing to consider on how to select capacitors is the tolerance. If your application is very critical, then consider a very small tolerance. Capacitors come with several tolerance options like 5%, 10% and 20%. It is your call which is which.
How to select bulk input capacitors?
There are two key factors for selecting bulk input capaci-tors: 1) overshoot and undershoot requirement of transient response; and 2) allowable ripple current requirement. The ESR of the bulk capacitor (ESRB) and the capaci-tance (CB) need to meet the transient response requirement.
Do capacitors meet non-Intel processor requirements?
Part 2 will describe capacitor types and value to meet output impendence requirements, and also high rate repetitive load transient specifications. Analytical and experimental results show that output capacitors selection is optimized for load transient and output impedance, to fulfill non-Intel processor requirements.
What type of capacitor should I use?
In both cases the capacitors should have low leakage current and have adequate precision. The best choices for feedback capacitors are class 1 ceramic capacitors, polystyrene film capacitors, and for high temperature applications, polycarbonate film capacitors.
What type of capacitor should I use for bypassing?
Bypassing capacitor selection depends on your requirement specifications. Low-frequency applications can be served by aluminum electrolytics or tantalum electrolytics. Class 2 ceramic capacitors provide a volumetric efficiency advantage for non-critical applications like higher frequency bypassing.

Battery Collection Tips
Step 1: Tape the ends of those batteries that require tapingStep 2: Place batteries in a 1-quart, zip-sealed, clear plastic bagStep 3: Place the plastic bag in your glass recycling bin for collection. If your bin is full of glass, place the bag of batteries on top.
FAQs about Battery Collection Tips
How should I store a battery?
To safely store a battery, you have two options: Option A: Bag each battery in its own clear plastic bag before placing it in a storage container. Or, Option B: tape the terminals with clear packing, non-conductive electrical or duct tape, keeping the label visible. Store the batteries in a cool, dry place.
How long should I wait before recycling batteries?
It's recommended to recycle batteries within six months after they are no longer in use. Be sure to bag or tape them before dropping them off at a recycling site. You can use our locator to find the nearest drop-off site. Spread the word about the importance of battery recycling.
How do you dispose of a single use battery?
Every year in the United States, millions of single use and rechargeable batteries are bought, used and recycled or disposed of in the trash. Batteries come in various chemistries, types and sizes to fit their use. Single-use batteries can generally be removed from the device when they stop powering the device.
What should I do with old batteries?
Do not throw away old batteries, especially those labeled as Lithium or Lithium-Ion. Contact Call2Recycle customer service at 1-877-723-1297, the manufacturer, or retailer for instructions. Aim to drop batteries to recycle within six months and ensure they are bagged or taped beforehand.
How do you dispose of a lithium battery?
Check for the word “lithium” marked on the battery. Do not put button-cell, coin, or lithium single-use batteries in the trash or municipal recycling bins. Check with Earth 911.com to find a recycling location near you. Button-cell or coin batteries can be a potential swallowing hazard. Be certain to store them out of the reach of young children.
Where can I recycle single-use batteries?
For single-use batteries, like AA, AAA, 9v, etc., you can drop them off at select Call2Recycle participating locations. For other options, contact your local community recycling center.
