FEATURES
High power in small packages (1 W/0207 size to
3 W/0617 size)
Different lead materials for different applications
Defined interruption behaviour
Lead (Pb)-free solder contacts
DESCRIPTION
A homogeneous film of metal alloy is deposited on a high
grade ceramic body. After a helical groove has been cut in
the resistive layer, tinned connecting wires of electrolytic
copper or copper-clad iron are welded to the end-caps. The
resistors are coated with a red, non-flammable lacquer which
provides electrical, mechanical and climatic protection. This
coating is not resistant to aggressive fluxes. The
encapsulation is resistant to all cleaning solvents in
accordance with IEC 60068-2-45.
Pure tin plating provides compatibility with lead (Pb)-free
and lead containing soldering processes
Compliant to RoHS directive 2002/95/EC
APPLICATIONS
All general purpose power applications

Solution to the problem of not receiving a single data packet in time when the serial port baud rate is changed to 9600 in CC2530
When debugging CC2530, it is found that when the baud rate is changed to 9600, the receiving DMA will start when a single packet has only 3 bytes.Therefore, the data packet is forced to be split into ...

Is there any good IC you can recommend?
I often connect PNP/NPN transistors into push-pull output to drive high-power loads. Is there any IC that only needs digital output and does not need analog output ? Please recommend it....

Can signaltap be set to automatically trigger after power-on? I encounter abnormal counting after power-on.
The debug script reads out that a register is 1 after power-on. This section of code is generated by a for loop. The initial values of the other registers are normal and there is no problem with the t...

Is the effect of dynamic loading of max541 driver different from that of integrating into NK?
max541 is a 16-bit DA chip. The wince driver written for this chip is integrated into NK and dynamically loaded with different effects. 1. After integration into NK, I found that max541 outputted 1.8V...
