Additional explanation for other models
EAM16FT1R00DES & ELR16FT1R00DES：
No detailed parameters were provided in the search results, but based on naming rules, it is speculated to be a product of the same series as Yineng, which may focus on conventional industrial applications (such as ELR series or high resistance type).
TSL120610F1R00P05Z：
No direct data found. The Tian'er TSL series is usually a thick film resistor with similar power and accuracy, but its surge resistance and temperature drift performance may be weaker than metal film/alloy foil models.
3、 Key parameter comparison and selection suggestions
The following table summarizes the main model differences:
|Model | Type | Core Advantages | Applicable Scenarios | Batch Unit Price (5000 pieces)|
|EGM16FT1R00DES | Surge resistant metal film | High pulse energy absorption | Industrial power supply/fast charging protection | Request for quotation|
|TGL120610F1R00P05Z | Surge resistant metal film | Vehicle grade reliability (AECQ200) | Automotive electronics | ¥ 0.37|
|TRL120610F1R00P05Z | Alloy foil | ± 50ppm low-temperature drift, high sampling accuracy | Precision current detection | ¥ 0.24|
Selection suggestion:
Priority anti surge model: If there is a risk of instantaneous high voltage in the circuit (such as motor drive, power input), choose the EGM or TGL series.
Priority accuracy and temperature drift: TRL alloy foil resistors are preferred for current sampling circuits (such as DCDC converters).
Cost sensitive scenario: For conventional applications, consider using Tian'er TSL thick film resistors (not recommended), but sacrifice some of their surge resistance performance.
4、 Application scenario extension
Industrial field: The EGM series is used for suppressing IGBT switch surges in PLC modules.
Automotive Electronics: TGL series is resistant to high temperature vibration and compatible with engine compartment sensor circuits.
Consumer Electronics: The TRL series achieves high-precision current feedback in fast charging and supports PD protocol high current surge.
Supply reminder: Currently, most models require a minimum order of 5000 pieces, with a delivery cycle of approximately 12 weeks. It is recommended to prepare materials in advance.
