How Hydraulic & Pneumatic Actuators Work – ATM | Digi-Key Electronics

Pneumatically-driven and hydraulic actuators generate linear or rotational movement using a liquid under stress, acting upon a piston or vane.When electromechanical actuators are either also sluggish or do not pack sufficient power to conquer a load, pneumatic and hydraulic systems can offer the rate or power to do the job. Each require accessory items such as valves, pumps, and limiters however the benefits are considerable with pneumatics giving rate and also hydraulics tremendous amounts of power.

Choosing Capacitors to Recap Old Electronics

Learn how to select capacitors [caps] for recapping old computers and vintage electronics. Understand which caps should be replaced, what the top brands are, how to use the Mouser website and evaluate the capacitor specifications. See how I pick caps for the Macintosh SE/30 motherboard.

🔍 INDEX
0:00 Intro
2:47 Which Caps to Replace
7:53 How to Choose Replacements
10:29 Measure Capacitance with an LCR Meter
13:15 Measure Physical Size with Calipers
18:45 Substitute Radials for Axials?
20:49 Buying Online: Mouser & Digi-Key
28:27 What is RoHS?
36:06 Capacitor Brands
40:05 Practical Example: SE/30 Motherboard
1:06:50 Organic Polymer Capacitors & “Hybrids”
1:11:50 Closing Words

🛒 SE/30 MOTHERBOARD CAPACITORS
I changed my mind. Rather than give you a Mouser Cart for the SE/30 motherboard, I instead provide links below to individual capacitors on Mouser. That gives you freedom to choose a Can-shaped capacitor for a stock look, or your favorite tantalum. The links below also let you choose the proper lead spacing for C11, which varies by motherboard version (2 types).

There are ten 47uF caps on an SE/30 motherboard: C1, C3, C4, C5, C7, C8, C9, C10, C12, C13.

I dislike liquid electrolytes, so I personally won’t use Polymer “Hybrid” Aluminum Electrolytics; but I listed that Hybrid cap because it technically will work fine and is superior to a regular aluminum electrolytic.

👉 For the “stock look,” go with the “Panasonic OS-CON.” They have the lowest ESR, but leakage is twice Polymer Tantalum.
👉 Want the lowest Leakage Current? Go with the “Kemet SOLID 25V Mid-height.”
👉 If you want the safest Tantalum below, in terms of being safer from a voltage spike that might kill the cap, the “AVX Polymer 25V Full-height” is ideal, albeit a bit pricey. Even a 16V Polymer Tantalum is “safe” with the SE/30 motherboard’s 12V though, so technically any of the Polymer Tantalums below are fine choices for that application.

47uF 16V Polymer Aluminum Electrolytic Caps:
• United-CC HYBRID! CAN-shape: https://bit.ly/3piGizK
• Nichicon CAN-shape: https://bit.ly/3nNl50j
• Panasonic OS-CON CAN-shape: https://bit.ly/37IlZWj
• Wurth CAN-shape (Cheap but High Leakage!): https://bit.ly/3phJyvc
• Murata Flat-shape (High Leakage! Harder to Solder!): https://bit.ly/3rh03tf

47uF Tantalum Caps:
• AVX Polymer 16V Full-height: https://bit.ly/3nJ8nzR
• Kemet Polymer 20V Short (harder to solder): https://bit.ly/3aCu7ta
• AVX Polymer 25V Short (harder to solder, but cheaper than Full-Size below): https://bit.ly/3mqIJhP
• AVX Polymer 25V Full-height: https://bit.ly/3aHCvrH
• Kemet SOLID 25V Mid-height: https://bit.ly/3riiC0d

✴️ NOTE: CAN-shaped Polymer Aluminum Electrolytics like OS-CON have higher leakage current than Polymer Tantalum, and much higher leakage than Solid Tantalum or regular fluid-filled Aluminum Electrolytics. That leakage spec doesn’t matter for the SE/30 MB, but is an issue in circuits where low power matters, like battery-powered devices.

Remaining 3 caps:
• C6: 1uF 50V Polymer Tantalum: https://bit.ly/3pjk3cU
• C2: 470uF Axial: https://bit.ly/38tPlXF
Choose only 1 of the following for C11 because there are 2 Lead Spacing variants (check your SE/30 motherboard to find out which you need):
• C11 (for 20mm lead-spacing holes): 220uF Axial Cap (8mm diameter): https://bit.ly/3pivCkm
• C11 (for 33mm lead-spacing holes): 220uF Axial Cap (6.5mm diameter): https://bit.ly/2WuQprW

⚠️ There are 13 caps in total on the SE/30 motherboard: 10pcs of 47uF and 1pc each of 1uF & 470uF & 220uF. The 4pcs of 47µF which see 12V are: C3, C4, C9 & C10.

⚠️ SOLDERING ADVICE! Keep your 300°C to 350°C soldering iron time to 3 seconds or less for either side of the capacitor, especially for Polymer types! The Polymer very slowly degrades over time, but heat accelerates that degradation!

What is an Inductor – Another Teaching Moment | Digi-Key Electronics

Inductors are one of the most common electronic components in the industry, comparable with resistors and capacitors but while they may seem simple, there’s more to consider than just their size and inductance value. Inductor resist increases or decreases in the current passing through them. This video explores back EMF, current flow through inductors and the magnetic field that results.
