# What component is this? Royal 283

I have no idea what this is and found nothing on google

• Looks like the datasheet is here: royalohm.com/pdf/product2017/CementAxialPRW.pdf – davidmneedham Jan 2 '18 at 19:33
• I feel sorry for Q2. Poor thing's been decapitated o_O. – Tom Carpenter Jan 2 '18 at 19:37
• @TomCarpenter Maybe just punishment for it killing the resistor. – Spehro Pefhany Jan 2 '18 at 19:40
• They really crowded that resistor though. I doubt it will actually take 3W in that spot. – Trevor_G Jan 2 '18 at 19:56
• Trevor is saying that resistor is packed in so tight to the components next to it that there's not going to be much air circulation to help cool the resistor. It might not be able to dissipate 3W of heat when one side of it is basically covered up. – JPhi1618 Jan 3 '18 at 20:48

It is an "axial-lead cement wirewound resistor" rated at 3W. Resistance is 0.22$\Omega$ +/-5%. Here is a datasheet.

I've been in their factory. ;-)

• LOL OK you win ;D – Trevor_G Jan 2 '18 at 19:34
• I put the datasheet in the comments 5 seconds after you... – davidmneedham Jan 2 '18 at 19:34
• @davidmneedham alas you get no rep for comments ;) – Tom Carpenter Jan 2 '18 at 19:35
• Well, Spehro, watching them being made is passive. Why, I've blown up a few, and replaced others in a repair;-) – glen_geek Jan 2 '18 at 19:42
• Once in a while a question is just fun. Fun pictures, fun comments, and correct and complete answer. +1 for question and answers ! – Marla Jan 2 '18 at 21:13

It is a 0.22 Ohm power resistor 3Watts

It might be a 220 mΩ, 3 W power resistor.

No its not it's a 3W 0.22 Ohm power resistor.

• What is the "No its not" referring to? Everyone seems to agree it's a 220 mOhm 3 W power resistor. – Olin Lathrop Jan 2 '18 at 20:41
• @OlinLathrop it was humor since I got in my answer 2s after you and Oldfart did I had to make mine look different ;) – Trevor_G Jan 2 '18 at 20:44
• Oh yes it is! (in honour of pantomime season) – Brian Drummond Jan 3 '18 at 17:28
• @BrianDrummond "BEHIND YOU!!!!!!!!!" ;D – Trevor_G Jan 3 '18 at 17:54
